Meal Prep Cost Calculator
Weight loss that doesn't survive contact with your bank account doesn't last. Enter what you actually spent and how many servings you prepped to see your true cost per meal — and what it saves you against eating the same meals as takeout.
Your week
This calculator works on the numbers you enter and typical US retail averages for the benchmark — it is not financial or medical advice. Prices vary by region and store.
What a Prepped Meal Actually Costs
Most home-prepped meals in the US land between $3 and $6 per serving. The spread comes almost entirely from the protein: the carb and vegetable parts of a container are cheap no matter what you buy. That's why the fastest way to judge a "budget" meal isn't its price per pound of ingredients — it's the cost per meal divided by the protein it delivers.
The math this calculator does is deliberately simple — weekly spend ÷ servings prepped. The discipline is in the inputs: use what you actually spent last week, and count the servings you actually ate from it. Estimating either one optimistically is how people conclude meal prep "doesn't save money" when their real leak is four takeout lunches a week that never made it into the comparison.
Reference prices: what the staples typically cost
Use this to sanity-check your weekly spend, or to plan next week's list against the cheap end of each row. Figures are typical US averages, rounded — your store and region will vary.
| Staple | Typical price | ≈ Cost per serving | Serving basis |
|---|---|---|---|
| Chicken breast, boneless | $4.20 / lb | $1.35 | 4 oz cooked (1 palm) |
| Chicken thighs, bone-in | $2.20 / lb | $0.90 | 4 oz cooked |
| Ground beef, 90% lean | $6.20 / lb | $1.65 | 4 oz cooked |
| Ground turkey, 93% lean | $5.00 / lb | $1.30 | 4 oz cooked |
| Canned tuna, in water | $1.30 / can | $0.90 | 1 can, drained |
| Eggs | $3.40 / dozen | $0.60 | 2-egg serving |
| Firm tofu | $2.60 / 14 oz | $0.90 | ¼ block cooked |
| Dried lentils | $1.80 / lb dry | $0.35 | 1 cup cooked |
| Brown rice | $1.60 / lb dry | $0.12 | 1 cup cooked |
| Oats, rolled | $1.40 / lb dry | $0.15 | 1 cup cooked |
| Frozen mixed vegetables | $1.60 / lb | $0.30 | 1 cup |
Compiled from Bureau of Labor Statistics average retail price data and USDA Economic Research Service food price aggregates. "Cost per serving" assumes standard cooking yield (roughly 25% shrink on meat, roughly 2.5× volume on dried grains and legumes) and a palm-size protein portion. Treat every figure as ±20%.
Read the table one way and chicken breast looks expensive; read it the useful way and the picture changes. Per serving, chicken thighs and lentils deliver protein for under a dollar, eggs for sixty cents — and even "expensive" chicken breast lands near $1.35, which is a fraction of any takeout protein. The expensive part of most people's food month was never the groceries. It was the $15 lunches between them.
Five levers that push the per-meal cost down
- Swap one protein per week to the cheap end of the table. Two chicken-breast dinners become two lentil or thigh dinners and the week's average drops visibly without changing anything else.
- Buy the dried or frozen form. Dried lentils and beans cost about a third of their canned versions; frozen vegetables match fresh nutritionally and don't rot in the drawer.
- Cook a whole chicken or a tray of thighs. Bone-in cuts are cheaper per pound, and the renderings and bones become soup base — a second set of meals from one purchase.
- Compare unit prices, not shelf prices. The bigger bag of rice is almost always cheaper per ounce; the family pack of chicken is cheaper per pound than the value pack. Check the small print on the shelf tag.
- Repeat staples across meals. A batch of rice does dinner containers and breakfast jars' oatmeal alternative duty; roasted vegetables appear in bowls, wraps, and omelets. Every repeat is a purchase you didn't make.
Frequently asked questions
How much does a prepped meal cost on average?
Most home-prepped meals in the US land between $3 and $6 per serving. A chicken, rice, and vegetables container is usually near the low end; salmon or beef pushes toward the top. The same meal bought as takeout or delivery typically costs $13 or more once fees and tip are included, which is where the savings in this calculator come from.
What is the cheapest protein for meal prep?
Eggs, dried lentils and beans, canned tuna, chicken thighs, and whole chickens sit at the bottom of the cost-per-protein-gram ranking. The right comparison is price per gram of protein, not price per pound — a cheaper cut with more bone and fat can cost more per serving of usable protein.
Should pantry staples count in the weekly grocery spend?
Yes, but amortize them. A bottle of olive oil or a jar of spices is used over many weeks, so divide its price by the number of weeks it lasts before adding it to your weekly spend. Entering one expensive pantry week as if it repeats every week will wildly overstate your cost per meal.
Does meal prep actually save money?
It saves through two separate mechanisms. The first is replacing takeout with home-cooked food — the comparison this calculator makes. The second is reducing food waste: USDA Economic Research Service estimates suggest roughly a third of the US food supply goes uneaten, and prepping a fixed list for the week means fewer impulse buys that rot in the drawer. The calculator only counts the first mechanism, so your real-world savings are likely higher.
